"Kosmos 954 (Russian: Космос 954) was a reconnaissance satellite launched by the Soviet Union in 1977. A malfunction prevented safe separation of its onboard nuclear reactor; when the satellite reentered the Earth's atmosphere the following year, it scattered radioactive debris over northern Canada, prompting an extensive cleanup operation." - WikipediaPlagiarism? Nah, why make things complicated? Wikipedia does a pretty good job summarizing the issue.
Someone graciously asked DND for all the information they had on the crash of Kosmos 954 in an access to information request (A-2013-00731); so I asked for a copy too. There are already books on the January 24th 1978 accident, but I'm looking through the file to try and figure out some information for myself; specifically, how much fuel didn't burn up, and how much radioactive material was left on the ground after Operation Morning Light I and II. Here is the information for your review.
